FAQ
Q1: Are you battery manufacturer or simply trading company?
Re: We are battery manufacturer, and we sincerely welcome you to visit our factory!
Q2: How do you make sure the quality?
Re: We will do the following works before assembling the pack:
a. Select capacity, same capacities cells for one pack
b. Measure the voltage, same voltage cells for one pack(difference is under 0.02v per cell)
c. Measure the inner resistance,same IR cells for one pack (difference is under 1m Ohm)
All above steps are very strict to make sure the pack performance is perfect.
Q3: What battery packs do you have ?
Re: Our main productus are 18650 battery pack, e-bike battery, lifepo4 storage battery, polymer battery, or any customized battery projects.
Q4: Do you accept OEM/ODM for battery?
Re: yes, please don’t hesitate to contact our sales team for more details.
